To all whom it may concern:

Be it known thatI, ll ANs Rasmussen, a citizen of the United States, and resident of Royal, in the county of Clay and State of Iowa, have invented a certain new and use-v ful Fuel-Filter for Carburetors, of which the following is a specification.

My invention relates to filters for fuel for placed.

Still afurther object is to provide such a devlce so constructed and arranged as to be mounted on any engine, and particularly shaped so as to be mounted on an automobile engine under the hood thereof.

Still a further objectis. to provide such a fuel filter device having'a clean out passage conveniently located.

My invention consists iii-the construction arrangement and combination of the various parts of the device whereby the ob jects contemplated are attained as hereinafter more fully set forth pointed out in my claims, and illustrated in'the accompanying drawings, in which:

F' are 1 shows a top or plan view of a fuel filter device embodying my invention.

Fig. 2 shows a side elevation of the same,

and Y Fig. 3 shows a vertical sectional View taken on the line 3-3 of Fig. 2.

ln the accompanying drawings, I have .shown a preferred form of my invention.

My device comprises a casing made of two parts, which i have indicated in the accompanying drawings by the reference numerals 10am] 11. The casing is comparatively thin rather than spherical or thick in order that it may be fitted into a small space under the hood ofan automobile.

The part 10 of the casing is provided at its open end with an annular shoulder 12, and beyond the annular shoulder is an externally screw threaded portion 13. The

part 11 is provided on its interior with an annular shoulder l-l and beyond the shoul-. der 1:1 is an internally screw threaded portion 15. The parts 10 and 11 may be screwed together and may be quickly and easily assembled or taken apart.

Between the portion 13 and the shoulder- 14 is placed a com mratively rigid partition or. disk 16, having near its upper end an opening 17 to permit the discharge of fuel.

Between the partition 16 and the portion 13, is secured the edge of a flexible filter mem ber 18, which is 'n-eferably ehamois and has some slack in its central portion.

Screwed onto the partition 16 on the side toward the filter member 18, is a spacing plug 19 for holding the central portion of the chamois filter member away from the partition 16.

Near the lower portion of the part 10 of the casing is a clean out tube 20 communicating with a discharge tube, 21 in which is a. valve 22. Formed on the upper portion of the part 10 is an intake passage 23, adapted to communicate with the gasolene supply tube 24:.

Formed on the lower portion of the part 11 is a discharge passage25, communicating with a gasolcne tube 26 adapted to lead to the carbureter.

In the practical use of my improved filter, the parts are assembled with the partition 16 and the filter member 18 in position. The valve 22 is closed, the passages 23 and 25 are connected with the tubes 24 and 26 reispcctivel y. The device may be placed close td a carburetor so that the fuel is fed through the tube 26 direct to the carbureter. Fuel passing into the casing through the tube 24 and intake passage 25 will drop tothe bottom of the portion 10 where sediment and solid matter will settle.

may be opened to remove sediment and the 1i kc, and. the filter may be flushed as often as desired. w

When desirable or necessary the parts 10 and 11 may 'be unscrewed and separated from each other for the removal, cleaning or replacing of the partition 16, the plug 19 or the filter 18..

In some cases it is desirable to replace the filter 18 frequently.

It will be understood that some changes may be made in the construction and. arrangement of the parts of my improved filter without departing from its essential features and purposes, and it is my intention to cover by this application and the patent to be issued thereon any such changes which may be included within the reason- 'able scope of my claims.

I claim as my invention.-

1. In a fuel filter, a casing comprised of two parts detachably connected together, a rigid partition between the parts, having an opening through it,.a filter device forming a partition mounted on one side of said partition, intake and discharge passages communicating with interiors of the respective caslng parts, a stop on said rigid partition for holding part of said filter device spaced therefrom.

2. In a fuel filter, a casing comparatively thin from side to side, comprised of two parts screwed together and formed with opposite shoulders on their interiors at their open ends, a rigid partition received between said shoulders, having an opening through it, a filter device having its edge secured between said partition and one of said shoulders, a stop on said rigid partition for bold ing part of said filter device sjpaccd from the partition, an intake passage coininunicating with. the upper interior of the casing part having the filter device, a valve cont1 olled, clean out passage in the -lOWer part thereof, and a discharge passage communicating with the interior of the other casing .part below the level of the opening in they rigid partition.
